.PREV DISCUSSION... /ISSUED 304 PM CDT Sun Apr 30 2017/

SHORT TERM (Tonight through Monday Night)...
Gusty northwest winds behind a strong cold front continue across
south central Texas this afternoon. Sustained wind speeds are
generally in the 10-20 mph, with a few gusts up to 30 mph noted
mainly along and north of I-10. Winds will continue to decrease this
afternoon and should become light and variable by mid-evening as the
pressure gradient eases. Clear skies are in store tonight and with
dry air in place, we will see overnight lows drop into the mid 40s
to lower 50s. Southerly winds return on Monday and with plenty of
sunshine, we expect highs in the 80s, except near 90 along the Rio
Grande.

LONG TERM (Tuesday through Sunday)...
On Tuesday, southerly winds will increase and we should start to see
a notable increase in dew point temperatures. Warm temperatures can
be expected on Tuesday with highs in the mid 80s Hill Country to
lower 90s Rio Grande. The weather pattern looks to become a little
more active on Wednesday as an upper level trough and associated cold
front move into Texas. The cold front will be fairly stout and with
the boundary set to arrive during peak heating hours, we could see
some strong to possibly severe thunderstorm development as the front
moves through our region. For now, we will keep rain chances fairly
high across the Hill Country, I-35 corridor and coastal plains
Wednesday afternoon and evening. Behind the cold front, we expect
below normal temperatures and dry weather across south central Texas
Thursday through Saturday. Toward the end of the forecast period,
another upper level low will be over the southwestern U.S. The exact
location of this low is uncertain as the medium range models are
consistent with a high-amplitude blocking pattern over the lower 48.
